Production Specification

The E2 brain board is an Ethernet-ready I/O and communication processor for analog I/O systems. Designed as a drop-in replacement for Opto 22's serial-based B2 brain board, the E2 supports both serial and Ethernet networking and multiple simultaneous protocols. The Optomux protocol is available over both serial and Ethernet; in addition, OptoMMP and Modbus/TCP are available over Ethernet.

The E2 is designed for customers needing to upgrade existing Optomux systems to use Ethernet networking while preserving existing I/O racks, modules, and field wiring.

Optomux
Up to 32 Optomux stations configured for multidrop can be used on a serial network of up to 1524 m (5000 ft.) total length. Up to 256 Optomux stations and longer line lengths can be used by installing network repeaters.
Up to 256 Optomux stations configured for repeat mode can exist
on a network.

* ±15 VDC ±0.25 V is required for the analog modules. Current depends on the number and types of modules installed. A 24 VDC power supply is required for analog modules that need a current loop source.

The E1 and E2 brain boards are Ethernet-ready I/O and communication processors for digital and analog I/O systems. Designed as drop-in replacements for Opto 22's serial-based B1 and B2 brain boards, the E1 and E2 support both serial and Ethernet networking and multiple simultaneous protocols, including Optomux, OptoMMP, and Modbus/TCP.

This overview describes the system capabilities of the E1 and E2 and illustrates methods for migrating existing Optomux systems to use Ethernet networking, while preserving existing I/O racks, modules, and field wiring.

E1 and E2 brain boards are Ethernet-ready I/O and communication processors for digital and analog I/O systems. Each brain board communicates with a host computer and performs control functions for its I/O points.

E1 and E2 brain boards are drop-in replacements for B1 and B2 Optomux brain boards. E1s and E2s offer both serial and Ethernet networking as well as multiple simultaneous protocols, including Optomux over both serial and Ethernet, Modbus/TCP, and OptoMMP (the memory-mapped protocol also used with SNAP Ethernet systems).

E1 and E2 brain boards can also be used with PAC Project software, such as PAC Control and OptoOPCServer.

ioManager is the software tool used to assign IP addresses and configure I/O points and system functions on most Opto 22 Ethernet-based hardware, including SNAP-LCE controllers: SNAP Ethernet, SNAP Ultimate, SNAP Simple, E1, and E2 I/O units; and SNAP-IT units. ioManager can also be used to directly read or write to these devices.

Use the steps in this technical note to configure I/O points and features for E1 and E2 brain boards used with Modbus/TCP, OptoMMP (memory-mapped protocol), OPC, or any PAC Project software. (You do not need this technical note if you are using E1s and E2s with Optomux only.)

IMPORTANT: You do NOT need to download this to operate E1 and E2 brain boards. It is a collection of source code intended for software developers only, and requires a solid understanding of the Linux operating system.

E1 and E2 brain boards run a Linux operating system (OS), and some software components used in this OS are licensed under the GNU Public License (GPL), the GNU Lesser Public License (LGPL), and other open-source licenses. This download contains the files Opto 22 is required to provide under these software licenses.

This file installs drivers for E1, E2, B1, B2, and serial B3000 and B3000-B brains. It is based on the "iolib_optomux.dll" library. This toolkit is recommended for all new Optomux-based applications because it supports Optomux communications over both Ethernet and serial networks.

The toolkit can emulate the interface that the earlier library "OptoMWD.dll" provided; however, using this interface is not required. This legacy interface capability is included to help an existing OptoMWD.dll user make a smoother migration to this newer toolkit. The legacy utilities OptoScan and OmuxUser are also included.

This toolkit is compatible with Windows XP and Windows 2000 operating systems. It is not compatible with .NET programming languages.
